You are asking the same questions I did at the time. Its happening to me right now as a matter of fact. It comes and goes. What I think happens and triggers it is if your phone tries to accept a message from the tower the same time as you get a phone call. Has to be during communication with the tower. This creates a "clog" at the tower and the only way to fix it is to reset the system that sets up communication with your phone. You phone does not set up any communications you do that manually when your phone is activated called a "profile" if you switch profiles it will fix the problem.

I have been through every level of tech support, and had phones replaced multiple times. I had hard reset, soft reset, changed roms. Everything I could possibly think of and nothing worked.

Sprint would go to the end of the world for you if it was happening on thier service but unfortunantly it is happening while roaming occurs. They do not and will not support it and pretty much tell you to go f yourself. I talked to probably 15 techs before I found one or two nice ones that were bored and intrigued about the issue and got me a few answers I was looking for.

They pretty much tell you sorry its roaming we can't check that network, but what you can do is buy an airwave system since you are having issues.... the only reason I am still with sprint is because I do cpu repairs and sometimes need to download drivers and software thru tethering and I'm not paying $30/month for plain internet on my cell phone when I can get it from sprint for $15
